So far, I am pleasantly surprised with the consistency of the pricing, the weekly notices of how much electricity I have used compared to the week before and the estimated current bill.It is nice to have that kind of detail where you don't end up shocked at the end of the billing cycle. ”

Constellation Gas

(5 / 5)

“
Constellation had the best price and the transition was seamless. I may change gas providers annually or as my contracts come to conclusion. I only change when I can find a better price. All the providers I have used have had comparable service and billing policies. Finding the cheapest provider is the challenge. ”
